As designed it is a useful booster amplifier for a QRP rig to add some extra 'presence' on 80 through 20 meters.  The cost mentioned is something like $30, particularly when the parts are bought 'in bulk.'  Note the amplifier can be used for all modes.  (While I do have the 100 watt amp in my K2, I have a lot of other rigs that would be nice to operate with an extra 10 dB more output power).

There is safety in numbers just in case one (or all) of our projects need a little debugging.  And perhaps someone among us knows how to tap holes (ok I have seen it done).

Let me know if anyone is game - and if we have a quorum we can move forward.

Curt;
Tapping holes is extremely easy, you just need a good (Craftsman) tap 
and die set and the appropriate drill size.
Also, Sears (Craftsman) now sell drill bits that are a combination drill 
bit and the tap so when you drill the
hole, it also taps the hole. This way you have the correct drill bit/tap 
together.
